Ah, this is one intriguing story. I like your style of writing, and the way you have set up the story with this opening chapter. The little details here and there are quite good - acting as fillers yet not coming across as boring. I like Drasina's character, you've crafted her well, and I am guessing she's Hermione with her memory modified/gone and her appearance changed. So if that's the case, you've done a good job of mixing old Hermione traits with new Drasina ones. I like Narcissa and Draco in your story, seems good, and I am loving the romance that will brew between Draco and Hermione/Drasina.

All in all, this was a well-written chapter and I quite liked it. In fact, I want to read more so I'm moving on to the next xD
